This invention relates tai -111 s. and more particularly, to composite rims and to means for I positively securing the. parts togetherl It is an object of the. presentinvention to provide a two pal-trim, which is normally adapted to be takenapart toj facilitate the mounting of a tire uponthe rim witlrmeans for securelyand positively loclnng the parts together.

vide a rim having an endles'sbase section and a removable splltsrde ring with a lock for positively securing the ends of the split side ring together and to thus. positivelymount the side rmg upon the basesectlon.

Another object of the invention isrto pro-' vide a lock fora side ring of a rim which is adapted to positively hold theends of the Another object of the-invention is to provide a lock for a rim section which is rattle proof and so designed thatjeven after wear the parts do not become noisy.

Another object of the invention '1srto pr0- vide means for securime the ends of a split 'rim member together, which means aredesigned to. stay positively locked under operating conditions. V

Another ob ec't o't'the invention is to provide means (for lockmga split side ring on an endless base which means are entirely inr dependent of the endless base.

'The lever. 28 is provided with a cam like extension 30 b:

sides of the link-21 are bent inwardly as illustrated" at 36 in Fig. 3. The bent in portions 36 of the link 21a're adaptedtobe received in the grooves 35 to assist in holding the mechanism inthe locked position and also H N ble rattles,'andto this end the bifurcated extensions 29 of the link "21 may beprovided with extending portions 40 which are bent inwardly at their sides as illustrated at 41 in Fig. 5. I V tend to clamp down aroundthe rounded lever 28 to hold the same in position and to prevent'rattles. However, the metal in the extensions 40 and in the link 21 is such that the bent in portions 41 can'be sprung back out of place by moving the lever 28 when it is "desired to throw the lever.

The projecting end of the lever 28 may be bent, as illustrated at 45 in Fig. 1, so that it will lie under the laterally projecting flange ofv the split side ring as seen from Fig. 3. I 7 I It-is believed that .the operationof the lock mechanism will be completely apparent from the drawing and the foregoing description. HOW8V61,'L brief resume thereof follows: U v

The side ring is first snapped into the gutter 12 ofthe endless rim base l0when the lockmechanism is in the opening position shown in Fig. 4. Thereafter, the link 21 andthe lever 28 are moved down adjacent the post 25 swinging about th-e pivot pin 22. The lever 28 is then 'moved inwardly, so that .the extension 30 thereof engages in the recess 26 0f the post 25, and further movement of the lever 28 about the pivot pin 27 causes the link 21 to move positively down over the post 25 sothat the inwardly projecting portions 36 of the link 21 snap into the side grooves on the post 25. As the lever 28 is pushed on down against the side ring, the cam toggle action of link 21 and lever 28 tends to draw the ends of the sidering very positively together and to thus contract the side ring very securely into the gutter 12 of the base rim 10. This very'positive contraction exactly aligns the side ring with the rim base insuring a very good support for a tire. *When the lever 28 hasbeen completely pushed-down in posi tion, the inwardly projecting portions 41 of the extensions 40 snap around the lever 28 in the manner shown in Fig. 5 to very securely hold the lever 28. This, together with the engagement of the projections 36 in the grooves 35 of the post 25 and the off center relation of the pivot pins 22and27 and the contact portion 84, insures that the mecha- -nismwill staylocked under the severest opcrating conditions.

In addition, these features also msure that the locking mechanism The inwardly bent/portions 41- the link cooperating with the lever for will be rattle proof and noiseless even after long use. 1

WVhen it is desired-to unlock the mechanism, the-operator insertsa tool behind the lever 28, which operation is facilitated bythefact that the boss 32 holds the lever 28 away fromthe side ring. The lever may then be pried awayfrom the side ring to the position shown in Fig. 4, at which-time the side ring may be readily removed from the endless rim base erating conditions. The mechanismcanbe quickly and easily operated to lock the ends ofa split rim member together or to unlock the same. It is compact and designed to fit into the rim structure in such a way that it can be mosteasily operated. This is achieved by a lateral movement of the locking levers.

'The mechanism, moreover, is positioned to be shielded from bumps'and'exposure.

In accordance with the patent statutes the best known form of the'mventlon has been illustrated in detail in the drawing and described above. However it isto be understood that this is for purposes of illustration only and that the scope of the inventionis defined in the appended claims.
